This quadrilateral has <u> 2 pairs </u>of parallel sides. Therefore, this quadrilateral is a <u> parallelogram </u>
===========================================
Explanation:
The arrow markers on the segments tell us which sides are parallel to one another. The single arrow segments are one parallel pair, while the double arrow segments are the other parallel pair.
By definition, a parallelogram has two pairs of opposite sides that are parallel. If only one pair of opposite sides were parallel, then we'd be dealing with a trapezoid. A square is special type of parallelogram in which all four sides are the same length, and all four angles are the same measure (all four angles are 90 degrees).
